Find the measure <br>someone please help ​
Ierofanga [76]

Answer:

m∠B = 31°

Step-by-step explanation:

First, find the measure of angle ACB by subtracting its supplement from 180 degrees:

180 - 113 = 77

m∠ACB = 77°

Then subtract both m∠A and m∠ACB from 180 degrees, since the interior angles of a triangle always add to 180°:

m∠B = 180° - 72° - 77°

m∠B = 31°

In a biathlon , jackson cycled 9 miles in 3/4 of an hour in the first event. He than ran, on average, 7 miles per hour slower in
lozanna [386]

Answer:

7.5 miles

Step-by-step explanation:

Given

  • In cycling,He covered 9 miles in \frac{3}{4} hours,Therefore his avg cycling speed, u=\frac{Distance}{Time} =\frac{9}{\frac{3}{4} } =12\frac{miles}{hour}
  • In second event, It took him 1\frac{1}{2} =\frac{3}{2}hours to complete,And his avg speed,v is  7\frac{miles}{hour} slower than in previous event

⇒v= u-7

v= 12-7

v=5

Distance covered in 1st event=9miles

Distance covered in 2nd event=Speed\times Time= 5\times \frac{3}{2} =7.5miles

Three less than the difference of 16p and 15p is equal to the difference of 3 and 1/2
Paraphin [41]

3 less: -3

difference of 16p and 15p: 16p - 15p = p

is equal to: =

the difference of 3 and 1/2: 3 - 1/2 = 2.5

p - 3 = 2.5

Isolate the p. Note the equal sign. What you do to one side, you do to the other. Add 3 to both sides

p - 3 (+3) = 2.5 (+3)

p = 2.5 + 3

p = 5.5

5.5 is your answer for p

hope this helps
